Try:
尝试：
$("#grid").getGridParam("reccount")
from the jqGrid documentation:
来自jqGrid 文档：
reccount(integer):
Readonly property. Returns the exact number of rows in the grid
记录（整数）：
只读属性。返回网格中的确切行数
Note also that, as Mike commented, you need to use the getGridParammethod with the recordsoption to retrieve a count of all the rows if you are using pagination.
另请注意，正如 Mike 评论的那样，如果您使用分页，则需要使用getGridParam带有records选项的方法来检索所有行的计数。

I tried reccount and I got zero but the following worked for me.
我尝试了 reccount 并且我得到了零，但以下对我有用。
<div>Total subscriber count: <div id="count" style="display: inline;"></div></div>
<br />
<div>
<table id="grid"></table>
</div>
<script type="text/javascript">
$(document).ready(function () {
$("#grid").jqGrid({
//Other stuff removed for brevity
gridComplete: function () {
$('#count').html($('#grid').getGridParam('records'));
}
});
});
</script>

This might be overkill and don't know if there's a better way, but this works for me:
这可能有点矫枉过正，不知道是否有更好的方法，但这对我有用：
$("#grid").getRowData().length

<a href="javascript:void(0)" id="g9" onclick="alert(jQuery('#list').jqGrid('getGridParam','records'));">Get number of records in Grid</a>

i get the grid data to array and then use the array length function to get the array length. It is equal for the number of record in the jqgrid.
我将网格数据获取到数组，然后使用数组长度函数来获取数组长度。它等于 jqgrid 中的记录数。
//get the grid data to array
var rows = $('#jqxgrid').jqxGrid('getrows');
// get the length of the array on array.length using javascript funcation
alert('' + rows.length);
